AT&T introduced a universal SIM card for the “Internet of things”



    Smart devices are good in that they are always connected to the network - either global or local (mostly Wi-Fi). Moreover, connection to the Internet in 99% of cases is via a local wireless network. But if for some reason the smart device is out of range of the local wireless network, then how can it connect to the Internet?

    But without a network connection, a smart device turns into a pumpkininto a regular piece of iron with limited functionality. In order to solve the connection problem, AT&T offered a universal SIM-card for connecting anything and everything to the Network. The size of such a card is only a few millimeters, and it is planned that the new card will be compatible with almost all cellular networks in the world, also meeting international standards.

    A device with a universal SIM card will always be on the Web, always available. The software of such a device can be updated at any time, and its functions can be controlled through the cloud. This connection method can be used for any device - from a fitness tracker to a smart motorcycle helmet.

    Currently, smart devices do not have a single standard for connecting to the Network, and mobile operators, fearing that home appliance manufacturers will create something of their own (as is the case with Amazon and Whispernet), and are proposing to use a unified SIM card.

    According to AT&T executives, the universal sim card will meet the GSMA specifications, and the use of this type of network connection will significantly expand the scope of the Internet of things.

    Such a SIM card will differ significantly from the SIM cards used in phones, and will not be delivered separately, but together with the device, while the card will be soldered in the board.
